Re: [babel] using #+call for inline results

[Eric Schulte <schulte.eric@gmail.com>]

Hi Eric,

So the problem is that the results are inserted as a separate block,
when you want them to be inserted inline?  If so perhaps using an
"inline" block http://orgmode.org/manual/Structure-of-code-blocks.html
would result in the desired behavior.

Please let me know if I've misunderstood the question.

Best -- Eric
